Fit Perfect on my 2005 GMC Sierra 1500 5.3L
My original GM belt went 18 years 174k miles. I tried to buy the original GM OEM belt again, but Amazon couldn't ship it for a few weeks. My old belt was so bad I didn't want to take a chance going on a trip at the end of the month, so I bought the 2nd best thing. AC Delco aftermarket, fits properly just like the GM belt did. No squeals. Likely the last AC belt I will ever change on my 2005 GMC Sierra 1500 SLE 4X4 5.3L B engine.

AC belt
This belt fits on my 2002 Chevrolet Silverado 1500 perfectly. I can’t remember the last time that i changed my AC serpentine belt as it is so far out of sight that i never think of it. My old belt was cracking severely and was on its last leg. This new belt restored the correct tension and eliminated slippage when my AC condenser would activate. It runs noticeably quieter when the AC is on and seems to be very durable and of great quality.

Change them often and early
Excellent quality. I ignore my vehicle manufacturer's 50K to 100K miles replacement recommendation, and replace my serpentine belts every 25K miles for one reason: Belts look great right up until the time they break.
